Abstract
In a liquid crystal display device having an alignment film subjected to an optical alignment process, the frame area can be reduced while maintaining the reliability of the sealing portion. To achieve this, in the display area, the alignment process is performed with UV light on the alignment film, to form an area in which the alignment film is not formed in the opposing first and second sides, and to form an area in which the amount of UV light irradiation on the alignment film is one fourth or less of the display area in the opposing third and fourth sides. In the first and second sides, the sealing material overlaps the area in which the alignment film is not formed. In the third and fourth sides, the sealing material overlaps the area in which the amount of UV light irradiation is one fourth or less of the display area.
